"The Retirement Black Box gives a practical and easy-to-understand overview of target-date funds—a blueprint for plan fiduciaries and advisors to thoughtfully evaluate their options." — Michael Goss President & Chief Revenue Officer, Wealthspire; Cofounder, President, and Managing Partner, Fiducient Advisors

"The Retirement Black Box shines an important light on the structural decisions inside target-date funds that many fiduciaries and investors rarely see. As an outsourced CIO working closely with financial advisors and retirement plans, I appreciate how clearly this book explains why glide paths, asset allocation, and fees can shape retirement outcomes over decades. Dr. Leite provides a thoughtful and practical framework that fiduciaries can use to better understand and oversee one of the most important investment decisions in the retirement system." — Al Cumplido, CFA Founder & Co-CIO, AMP Consulting Group

"Target-date funds have quietly become the default retirement vehicle for millions of Americans, yet most investors have only a vague sense of how they work. Dr. Leite’s new book changes that. With clarity and care, he strips away the jargon—glide paths, equity roll downs, to-versus-through construction—and replaces it with plain language and intuitive examples that finally make these products feel knowable. The Retirement Black Box is a rare finance book that respects the reader’s intelligence without demanding a CFA to follow along. Whether you are a plan fiduciary, a curious investor, or advising clients with decades of retirement savings at stake, you will close this book with a sharper understanding of what your target date fund is really doing on your behalf—and why it matters." — Stephanie Pierce Deputy Head, BNY Investments
